An unusual class of nanoscopic, ring-shaped, single-walled biopolymers arises when alphabeta-tubulin is mixed with certain small peptides obtained from various marine organisms and cyanobacteria. The single-ring structures, whose mean molecular weight depends on the specific peptide added to the reaction mixture, usually have sharp mass distributions corresponding, e.g., to rings containing eight tubulin dimers (when the added peptide is cryptophycin) and 14 dimers (e.g., with dolastatin… CONTINUE READING
